Description

The USA Standard Gear open spider gear set is designed to replace worn or damaged spider gears within a Chrysler 9.25" ZF rear differential. This set is specifically engineered for 2011 and newer Chrysler 9.25" ZF rear axles with 31-spline shafts. It is crucial to note that this is an open differential spider gear set and is not compatible with limited-slip differential units. The kit contains all necessary components for replacement: two side gears, two pinion gears, a cross pin shaft, a cross pin bolt, and spider gear thrust washers. This ensures a complete solution for restoring proper differential function. This spider gear set is compatible with 2011-2018 Ram 1500 models (Rear Axle), including 4WD and RWD variants, provided they do not have a limited-slip differential. It is also confirmed to fit the 2010 Dodge Ram 1500 (Rear Axle) with the same qualifiers.
